Distributions or dynamics of (meta)populations, species or communities
A main research interest is to investigate the relative importance of environmental conditions, species interactions and (meta)population processes, such as dispersal, in explaining the spatial distribution or dynamics of (meta)populations, species and communities. The work on single species includes investigating new approaches for estimating the rate of metapopulation dynamics using very limited amount of data, e.g. only the distribution pattern of a species among its habitat patches. We mainly do statistical modelling of field data on species occurrence or dynamics, but we also conduct field experiments and population genetic studies. Sessile (vascular plants, bryophytes, fungi, lichens) as well as mobile (insects, birds) species are studied, mainly in forests.
Levels and Dynamics of Ecosystem Services
We investigate the relative importance of local environmental conditions, tree species richness and composition in explaining levels and dynamics of ecosystem services on different spatial scales. Provisional, supporting, regulating and cultural services are studied. We answer these questions by statistical modelling of field data, typically large-scale monitoring data, such as national forest inventory data.
Response of species or ecosystem services to scenarios of land-use or climate change
Another main research interest is to investigate how (meta)populations, species, communities and ecosystem services may be affected by scenarios of future forestry or climate change. This includes simulating scenarios (answering What if?) and optimization (answering How?). The main spatial scales studied are the landscape and national scales, but we also consider the EU and global scales, see e.g. Horizon Europe and ERA-Net projects below. The scenarios simulated are formulated together with a range of stakeholders and with our research partners. The questions are answered using models that we develop in the group or available models and tools, e.g. Heureka for forestry planning.
Usefulness of citizen science data for modelling and scenario analysis
The final main research interest is to investigate the usefulness of volunteers’ reports of observations of species to open-access websites, such as Artportalen or GBIF, for answering basic and applied questions. We particularly evaluate them for predicting species distributions, projecting species occurrence into the future, and for population trend estimation.
